tools: use __pa() in virt_to_phys()
With 32-bit pointers and a 64-bit phys_addr_t, GCC warns about the
pointer-to-integer cast in virt_to_phys(). It can also sign-extend
pointers whose top bit is set, turning 0x80000000 into 0xffffffff80000000.
Use __pa() to convert through unsigned long before widening the result.
This preserves the unsigned pointer value and matches the other address
conversion helpers.
